LUBRICATIG DEVICE.

To all whom it may concern: i

Be 1t known that 1Rn1N1ER FREDERIK OTTO GROENINX VAN ZonLEN.. a subject of the Queen of the Netherlands, and resident of Helder, Netherlands, have invented certain new and use't'ul Improvements in Lnbrieating Devices` of which the following is a specification.

The invention relates to a. device for automatically lubricating` motors, machines, machine parts etc., which run in cases, such as for instance automobile motors; the invention serves on the one hand for sufficiently lubricating the parts of the machine, and on the other hand to produce an automatic delivery of the lubricant according to the consumption from a special supply vessel. Further the device is so constructed that dashing about ot' the lubricant, which causes especially with certain kinds of oil the formation of foam, is avoided.

The new device consists essentially of an oil chamber connected with the motor, or machine case, by means of a channel or the like. On this chamber a dropping' vessel is detachably arranged, the outletvrotl which can be conveniently closed. The/oil is prevented from dashing about by meansl of special contrivances. such as suitably arranged partitions, or a suitable formation. and arrangement ot theyehannel connecting the machine case and the oil chamberl The yformation `oi: foam cannot.. theret'ore take place. I

In the accompanying drawing' one torni of construction of the new device as applied to a bicycle motor is shown.

To the case a, in which the crank of the motor rotates, the oil'chamber'rl is connected by means of the channel c.- On the oil chamber Z is situated the dropping vessel which is screwed to the chamber so that it can be adjusted in height. The outlet z' can be closed by means of a seal 71:.

Z is an air tube and m a zf ,rlass for viewing,r

f the height of the oil, Which are both con- Specification of Letters Patent. Patented Dec. 21, 1909. Application filed May 15, 1907. Serial No. 373,792. l

These partitions have openings allowing the, lubricant to pass through. The rotation of the crank b causes the oil to be distributed to 'the other parts of vthe motor cylinders etc.) and as soon as the level of the oil is reduced the oil drops down Jfrom the vessel the supply beimgY periodically sup-plemented through the opening lf, closed by the screw g.

It is obvious that'the arrangement and formation of the single parts of the device may differ from the example shown in the drawing,r without the scope of the invention being;` exceeded.. 'i

I claim:

1. The combination of a ease in which a machine works, with an oil chan'iber. a channel connecting'I said oil chamber with said case, transverse partitions in said channel, said transverse partitions havingY openings, a dropping vessel adaptedto supply lubricant to the'oil chamber, a'sight glass for ascertaining the height-otl the lubricant in the oil chamber, an air tube connected with the qil chamber, and an adjustable seal adapted to regulate the outlet of the dropping` vessel, substantially as set forth.

Q. The comliination ot a case in which a machine works, withan oil chamber, a chan nel connectilne'l said oil chamber with said case, transverse partitions in said channel, said transverse partitions having openings, a droppingl vessel adapted to supply lubricant 'to the oil chamber` said dropping vessel being adjustable in height, and detachable from the oil chamber, a sight glass for ascertaining the height` of the lubricant in the oil chamber, an air tube connected with the oil chamber, and an adjustable seal passing through, the bottom ot the oil chamber, adapted to regulate. the outlet of the dropping' vessel, substantially as set forth.

In testimony whereof I have hereunto signed my'name this 24th day of April 1907,

/ in the presence of two subscribing witnesses.
